Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

A good kata. However more tests should be added. I accidentally submitted solution that returned true for ))
Seems the random tests are broken:
[ 1012, 16, 88, 22, 23 ]
✘ Expected: 45, instead got: 38
Passed all tests, when trying to submit the final solution, I am getting "There was an issue submitting your final solution". However kata appearing as completed, but solutions are not available.
